Microtonal music is a term for music which uses intervals smaller than the standard semitone, although it is also generally used to describe any music which is not based on the twelve-tone equal tempered system which prevails in Western music. Microtonal compositions present a huge challenge to performers, requiring them to re-train their ears to new intervals. Due to the inherent difficulty in playing microtonal music, it is usually performed/produced using specially constructed microtonal instruments or computer synthesis.

The Rosegarden Codicil is a practice tool integrated into the Rosegarden sequencer framework. It aids the process of learning a new tuning by providing the performer with real-time feedback regarding the performed pitch, and a post-performance analysis of pitch intonation which allows the archival of multiple performances. It is part of the Microtonalism project.
